I agree. I have a few illnesses diagnosed by specialists as stress related - all were pretty much totally resistent to medication. I had headaches, daily, for years and years in my childhood an adolescence. I still suffer, but it is better than it used to be. Instead, I seem to have swapped one health problem for another, with severe IBS through late teens up until I was 20. Again, diagnosed as stress related, and treatment only helped a little. This is now under better control, though I still suffer... literally as that became less severe, my sleep problems (which have been around for years too) have become severe. Again, a stress related problem. Currently, I'm trying to work on my PTSD to rid myself of physical stress as well as mental. I think until I do that... I will move from one to another severe health problem, or end up with multiple.

It's awful. But your body is telling you something. It may be that the trauma is coming out in the headaches, I agree.... but I'm not sure I agree that the headaches are filtering out the problem in their own way, as some sort of pressure release...I think it is more that it is pressure overload. Finding solace and peace from your trauma whatever way you need to will probably solve the problem. Easier said than done... my god I know...! But a fact.
